IMPROVEMENT IN BoMB-LANCss..

Specification forming part of Letters Patent No. 222,003, dated November25, 1879; application filed June 19, 1878.

To all whom it may concern:

Be it known that I, JUNiUs A. BRAND, of the eityvof Norwich, in thecountyr of New London and State ot Connecticut, have invented certainnew and useful Improvements in BombLances, of which the following is aspeeilieation, reference being had to the accompanying drawings, forminga part of this specification.

Figure 1 is a longitudinal `central sectional view. of the bomb-lance.Fig. 2 is a rear end view oi the same. Fig. 3 is a rear end view of theprimerplate and primer.

This in'vention relates to that class of bomblances that are projectedor tired from a gun; and its object is to construct and arrange `abomb-lance the fuse of which shall be ignited by the explosion ot'l aprimer, which is exploded by the blow of a tiring-pin operated upon bythe discharge of the gun; also,A that it shall be water-proof and notliable to explosion from careless handling, all of which is hereinaftermore fully explained.

. Preferably this boniblance is composed of four "parts or pieces, whichI designate as the shell A, fuse-tube B, primer-plate e, and head O,alll being constructed and arranged as shown idiEigs. l, 2, and 3, andhereinafter described.

The* shell A, Fig. 1, is constructed with a cavity for the reception ofa charge ot powder forf'lthe purpose otA exploding the-shell. 1t

also'has a screw-thread cut upon a portion of its inner circumference.The fuse-tube B, Fig. 1, has a screw-thread at each end out upon itsouter circumference. AThe primer-plate a., Figs.

1 and 3, is a metal disk or plate holding seeurelyV in itsicenter'theprimer lt alsoV ,l'orms a solid bed or anvil, so as to insure the`explosion of the primer when struck by a suit# able innig-pim The headC, Fig. 1, is constructed with a cylindrical recess in its front end,having a screw-thread eut upon its surgflafeegyalsmwith a centrallongitudinal cylindrical passage of varying .diameter through it. Aportion of said passage is occupied by the iring-pin c held rearward bythe spiral vspring It, as shown in Figfl.Y The rear end of said passage,as

shown in'Figs.-1 and 2, is filled and hermetically closed by the thinmetal disk l), Fig. 1.

In asselnblin g this bomb-lance the cavity `in the shell A-is lilledwith powder, and the fusetube B, containing the fuse, is screwed tightlyinto the rear end of the shell A, as shown at i, Fig. 1. Y, v

The primer-plate ,containing the primer. k, is placed in position uponthe rear end ofthe fusetube B, as shown in Fig. 1, and the head Cscrewed upon the rear end or" the fuse-tube B, as shown in Fig. 1, thussecuring in position the primer-plate a. and completing the bomblance.

The usual rubber or metalfeathers or .guides are placed around thei'use-tube. IThis bomb lance can be exploded only by a direct forceapplied to the rear end ot' the head C sui cient to suddenly break thethin metal disk b and drive vforward the firing-pin c, thereby explodingthe primerk, and thus igniting the fuse c, which, at the proper time,iguites the powderiin the shell A.

The force of the explosion of the powder in the gun upon the thin metalVdiskb in the rear end of the head O is suliieient to accomplish thedesired result, as above stated.

The disk b, after being inserted in the head G, is hernietically sealedin the recess for its reception, in order that no moisture or water orother matter may gain access to the rin gpin or the primer,'or thesockets in which they are situated. The spring It keeps the tiringpin upto the disk, and from being aceidentally driven forwardagaiust theprimer.

Having thus described my invention, what I claim as new, and desire.to-secure by Letters Patent of the United/States, is-' l. As applied toor for use with the fuse tube ot a bomb-lance, the coi-nbi'ation of thehead U, provided with the primer and diskreceivingreeess, arranged in itas set forth, with the primer 75, the firing-pin c, and the separatesealingdisk b, all being' andfto' opcrate substantiallyY as specified.
